# oeli 0.4.1

* Removed HMM code and `plot_sequence()` function (both do not really fit in this package).

* Added more vignettes to illustrate use cases.

# oeli 0.4.0

* Fixed bug in checks for matrices by checking for `NA`, `NaN` and infinite values.

* Increment RoxygenNote to 7.3.0.

* Added function `system_information()` that returns some general system level information.

* Added functions `check_list_of_lists()`, `test_list_of_lists()`, and `assert_list_of_lists()`.

* Added functions `check_numeric_vector()`, `test_numeric_vector()`, and `assert_numeric_vector()`.

* Fixed a bug in `merge_lists()`, where `NULL` elements got erroneously ignored.

# oeli 0.3.2

* Fixed bug in `function_arguments()`.

# oeli 0.3.1

* Fixed https://github.com/RcppCore/Rcpp/issues/1287.

# oeli 0.3.0

* Added function `check_date()` which checks if the input has the correct date format.

* Added function `find_closest_year()` which finds the closest year to a given date.

* Added function `match_numerics()` which matches the indices of two numeric vectors as good as possible (that means with the smallest possible sum of deviations).

* Added function `simulate_markov_chain()` which simulates a Markov chain.

* Added function `sample_transition_probability_matrix()` which samples a transition probability matrix.

* Added functions `test_covariance_matrix()`, `test_correlation_matrix()`, `test_transition_probability_matrix()`, and `test_probability_vector()` (which are the "test" version of the corresponding "assert" functions).

* Added argument `tolerance` for covariance matrix, correlation matrix, transition probability matrix, and probability vector check functions to account for machine epsilon and avoid false positives.

* Added functions `ll_hmm()` and `simulate_hmm()` to compute log-likelihood and simulate data from hidden Markov model.

* Added argument `on_time_out` to function `timed()` that defines what action to take if the evaluation time exceeded (error, warning, or silent).

* Added support to select `identifier = "all"` in `Index` object and to suppress warnings (if unknown identifiers were selected) (globally) via the `$hide_warnings` field.

* Added argument `logical` to `Index` object to combine multiple identifiers either with logical and or logical or.

* Added function `unexpected_error()` that handles an unknown error.

* Added function `group_data_frame()` that groups a `data.frame` according to the values of a column.

* Added function `delete_data_frame_columns()` that deletes columns of a `data.frame`.

* Added function `renv_development_packages()` that creates a file that loads development packages so that `{renv}` can detect and write them to the lockfile.

* Added function `plot_sequence()` that plots a sequence of numbers.

* Renamed `Index` -> `Storage`.

* Initialized a package website with `{pkgdown}` and started to add vignettes.

# oeli 0.2.0

* Added function `timed()` which evaluates an expression and interrupts the evaluation after a defined amount of seconds.

* Added function `do.call_timed()` which measures the computation time of a `do.call()` call.

* Added function `try_silent()` which tries to execute an expression and returns a string with the error message if the execution failed.

* Added R6 object `Index` that provides a simple indexing interface for list elements.

* Modified `basic_package_sticker()`: Option to add brackets to package name, now scales font, the function is no longer exported.

* Added function `function_body()` which extracts the body of a function.

* Added function `permutation()` which creates all permutations of a given vector.

* Added function `variable_name()` which tries to determine the name of a variable passed to a function.

* Added function `function_defaults()` which returns the default function arguments.

* Added R6 object `Dictionary` that provides a simple simple key-value interface.

* Added function `merge_lists()` which merges `list`s based on their element names.

* Renamed arguments in function `timed()`: `expr` -> `expression`, `secs` -> `seconds`.

* Added argument `units` to function `do.call_timed()`.

# oeli 0.1.0

* Initial CRAN submission.
